DRIVING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 761,213, dated May 31 I904. Application filed February 4, 1903. Serial No. 141,841. (No model.) i

To aZZ whom, it may concern:

Be it known that 1, CHARLES A. EoK, a subject of the King of Sweden and Norway, and a resident of Belleville, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Driving Mechanism, of which the following is a specification.

My invention relates generally to driving mechanism, and is especially adapted to be used in connection with centrifugal separators.

- I shall describe a driving mechanism embodying my invention and afterward point out the novel features in the claims.-

In the accompanying drawings I have shown my invention in connection with centrifugal separators; but it will of course be understood that I do not limit myself in its application to any particular-machine.

In the said drawings, Figure 1 is a general view showing a driving mechanism as applied to a centrifugal separator. Fig. 2 is an enlar ed sectional view on the line a; w of Fig. 1. 3 is a detached view of the horizontally-disposed spiral gear and pinion shown in Fig. 2. Fig. i is a sectional view on the line 3/ of the upper bearing of and adjacent parts surrounding the vertical shaft carrying the horizontally-disposed spiral gear.

Similar letters of reference indicate corresponding parts'in the different views.

A represents a hollow base portion provided with inwardly-projecting lugs a.

Bis a framework composed of two vertically-disposed hollow and cylindrical casings b and 6 open at both ends and constructed in any suitable manner, but preferably formed integral with a connecting-arm 6 as shown in the drawings, and secured in position on the base A by the bolts (0 passing through the lugs a. The bowl C extends vertically through the casing b and is removably mounted in any suitable mannerfor instance, as shown in my application for Letters Patent filed on the 19th day of November, 1902, Serial No. 131,926. At the upper end of the casing 6 are furthermore the usual covers, as c and 0 andv an intermediate tank, as 0 The driving mechanism D consists of the 5 following elements: On the vertical shaft 0 of. the bowl C is mounted the spiral pinion d, meshing with the spiral gear d mounted on the horizontal shaft d in the base A, which also carries the spiral pinion d. Mounted in the base A and in the bearing Z) of the casing b is the vertically-extending shaft (i carrying at its lower end the horizontally-disposed spiral gear d, meshing with the pinion cl. At its upper endthe shaft d carries the bevelpinion d meshing with the bevel-gear d mounted upon the horizontal shaft d, having the crank d or other suitable device for imparting motion. The upper end of the casing b is closed by the cap 6 carrying the bracket 72, supporting the tank 5 By removing the bolts a the casings b and b can be removed, carrying the bevel-gear d and pinion (Z which latter simply fits around the square end (Z of the shaft 01 without being securedto the same and rests on the bracket 5 of the bearing 6. This is a very convenient construction, as the parts are thereby easily separated when for any reason it is desired to do so. A further advantage resides in the factthat by having the vertical shaft 03 the length of the bowl and other parts can be increased or decreased in making the different sizes of machine without it being necthe handle or crank al is turned to operate the machine the gear d will move the clutchsurfaces d of the pinion (F into engagement with the clutch (Z as shown in Fig. 2. When the handle is turned in the opposite direction,

the gear cl will move the pinion d away from the clutch 03 as shown in Fig. 3. Furthermore, after power has been applied and when it is no longer applied the rotation of the clutch c 12 will have the effect of pushing the pinion d away from it and of releasing it until it does not contact with the said clutch any longer, thus doing away with the noise usually caused by such machines. In addition to this it prevents any sudden jar of the machine or accident which might occur if the handle should be grasped while the machine is rotating. To prevent the pinion (Z from moving too far, a stop, as (Z is provided.

It will be understood that the invention centers around the spiral pinion d, carrying the clutch-surfaces (Z which is moved positively into and out of engagement with the clutch el by means of the gear cl. It is also obvious that the pinion 6F, carrying the clutchsurfaces cl, will disengage itself automatically from the clutch (Z if the momentum is sufficient when power is no longerapplied after it has been applied. I

The terms vertical shaft and horizontal shaft are of course entirely arbitrary, they being merely used to indicate that power is applied from one shaft to another shaft located at right angles to the first shaft.

Any gear could of course be used to impart the motion from the shaft (Z to the vertical shaft carrying the bowl.

Having thus described my invention, what a I claim isr 1. In a driving mechanism, the combination of a shaft, a clutch mounted fast on the same,

a spiral pinion mounted loosely on the said shaft and provided with clutch-surfaces, a spiral gear adapted to engage with the said spiral pinion to positively move the said pinion toward and away from the clutch depending upon the direction of the movement of the spiral gear and a stop for limiting the motion of the spiral pinion away from the clutch.

3. In a driving mechanism, the combination of a shaft, aclutch mounted fast on the same, a spiral pinion mounted loosely on the said shaft and provided with clutch-surfaces, and a spiral gear adapted to engage with the said spiral pinion to positively move the said pinion toward and away from the clutch depending upon the direction of the movement of the spiral gear, the said spiral pinion further moving away from the clutch, if the momentum is sufiicient, when power is no longer applied and after it has been applied.

4. In a driving mechanism, the combination of ashaft, a clutch mounted fast on the same, a spiral pinion mounted loosely on the said shaft and provided with clutch-surfaces, a spiral gear adapted to engage with the said spiral pinion to positively move the said pinion toward and away from the clutch depending upon the direction of the movement of the spiral gear, and a stop for limiting the motion of the spiral pinion away from the clutch, the said spiral pinion further moving away from the clutch, if the momentum is sufficient, when power is no longer applied and after it has been applied.
